I was taking up some flooring to help put down some laminate for a friend and at first I thought it might be termite damage but then after looking, it appears to be ant mounds. It smells like one anyhow from running over them with a mower from time to time.

They claim they have never noticed it before and it is a spare bedroom with little use and it has recently just starting turning cold down here. It is only on the exterior walls so I’m guessing the ants made there way in when it turned cold.

Anybody got ideas on how to stop them from coming in? Never did see any live bugs or anything though. When we vacuum them up, you can tap on the wall just above where the dirt is and more will fall. We took the siding down on the outside of the house to look for any hole in the OSB and couldn’t find any. I’m not even really sure how they are getting in because at first I thought it would just be between the foundation and bottom plate but then I’m not sure why if you tap on the wall more will fall down unless they have mounded the dirt up far enough to get above the bottom plate.

Anyone ever dealt with something like this?

Looks like a good time to call in a professional.

I sprayed a carpenter ant colony that had tunneled one hole near a window sill and kept hauling their chewings and throwing it out of that hole. I kept spraying that hole, inside the house, as well as the perimeter outside. I eventually drilled holes through my wood siding and sprayed ant killer into those holes as well. It took me two years, but eventually, after killing dozens at a time (as they threw their dead out the hole), it all just stopped. I had won, but like I said, two years of fighting them is a long time. I saved a lot of $$$ by DIY, but what a PITA!

What that is is not good. If it is ants or termites does not matter.. every time “stuff comes down out of the wall” in my experience, something is eating the house, or causing damage.
